To set the scene we see an eight year old boy named Hayato Gokudera and his 'piano teacher' seated at a grand piano in a spacious room made just for learning the melodic instrument.
"You're learning faster than I thought," the teacher smiled brightly, genuinely impressed by the learning speed the child, her child, was at.
"Thanks," Gokudera grinned flashing her a 1000 watt smile showing her his missing front teeth.
He then returned to the piece he had been currently playing. When he played the notes he donned a more serious mien as he focused on the notes and the harmonious music that emitted from the large instrument.
Gokudera's mother looked fondly at her little prodigy wishing she could tell him the truth, but she knew she couldn't. It was too risky, to dangerous.
"I like this song, it tells me a story." Gokudera whispered as he played the last few notes.
"This is my new favorite song, let's play it everyday okay?" Gokudera asked staring hopefully at his piano instructor.
"Okay," she smiled, she too enjoyed the song.
Now we see a present Gokudera, age 15 standing in a semi-vacant room that held nothing but a scarcely polished piano.
Sitting on the bench the teen lightly brushed his hands along the keys, without pressing them, enjoying the feeling of them beneath his fingers.
He hadn't played in seven years but he still remembered each and every key.
Digging into his jeans pocket he fished out a folded piece of paper. He then proceeded to unfold it and smooth out the creases so it didn't fall forward. Placing it on the built in music stand, he prepared to play.
With a quick skim of the notes he was good. They were burned back into his memory. His hands then began moving on their own accord, fingers flying as he played the piece. A flurry of semi-high notes and low notes. Altogether a beautiful piece.
Once he was finished and taking a pause to rest he heard the sound of excited clapping. Gokudera turned around so fast he almost flew off his bench.
Standing there was his baseball idiot clapping widely, a huge grin plastered on his face.
"That was awesome!" he exclaimed his eyes sparkling comically in amazement.
"Tch, shut up," Gokudera mumbled turning around so that he was facing the piano in an attempt to hide his blush.
Running over, Yamamoto sat down next to his boyfriend and scanned the sheet of music perched on the stand.
"Can you play it again?" Yamamoto asked a serious expression crossing his face.
Instead of his usual protesting Gokudera relented and began to play-since he did love the song.
As he played he felt the heated stare of the brunette sitting next to him. Soon a pair of long semi-muscular arms wrapped around his middle.
Spluttering Gokudera stopped playing, his face burning.
"Why are you doing that for?" Gokudera mumbled still blushing.
"Can you teach me...to play this song?" Yamamoto asked seriously as he stared fondly at the silver haired boy in his arms.
Gokudera's face combusted, a blush reaching from his face to his ears. He attempted to answer but at the moment couldn't form coherent sentences.
Since he couldn't speak he decided to use actions instead. Unwrapping Yamamoto's arms from around his waist, he took his hand and placed one finger near the first note.
Yamamoto grinned widely and pressed down on the key, the white object eliciting a noise.
Turning towards Gokudera, the tan boy kissed his paler companion on the cheek.
"Gokudera smiled uncharacteristically shyly, retook his hand in his and placed it on the second note.
This song tells me a story...a story of two lovers.
